Salt is a good absorbent for all sort of liquids.
You can try to keep salt box opened in a room with hight humidity. After a while you'll find your salt soaked so much water from the air so it began to dissolve.
Or just spill a little of EVOO onto your clothes and see the small nasty oil stains, feel upset about it, then put that cloth onto a desk, pour some salt on top of it covering that oiled spot(s), tap salt a bit with fingers, and wait for a couple of hours. Then clean stuff and see the difference. This is a pretty good method to light such stain if you unable to wash item right after such accident. And of course, earlier you put salt onto, better will be a result.
